Y. -VENTI-LATOR FOR SLEEPING-CAR BERTHS.

Patented Mar. 13, 1917.

Application filed November 10, 1915. Serial No. 60,743.

To all whom t may Concern:

Be it known that I, lhuonv P. BAKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of "Illinois, have invented certain new and useful Improvements in. Ventilatore for Sleeping-Car Berths, of which the following is a specification.

This invention relates to ventilators and more particularly to a ventilator designed primarily for employment in Ventilating the berths of sleeping-cars, the ventilator being designed to be arranged within the curtain, or, if desired, within the window panes, of the berths and being so constructed that it may be opened or closed as may be desired, by the occupant of the berth. ,Y

It is one aim of the invention to soconstruct the ventilator that while it will be adapted to admit the desired amount of air and to conduct foul air from the vicinity of the berth, will not permit anyone standing in the aisle of the car obtaining a view of the berth. L s

Another aim of the invention is to so arrange the ventilators that distribution of fresh air may be most advantageously secured. v

Another aim of the inventionis to provide a ventilator for the purpose stated so constructed that it will not interfere with the folding and storing away of the curtain in which it is arranged. l

ln the` accompanying drawings:

Figure 1 is a perspective view of a vp0rtion of a sleeping car illustrating the manner of arranging and using the ventilator embodying the present invention.

Fig. 2 is a vertical sectional view through one of the ventilators.

Fig. 3 is a front elevation thereof.

Fig. 4 is a view Y similar to Fig. 3 illustrating a slight modificationv of the invention.

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 4.

Fig. 6 is a view similar to Fig. 2 illustrating a further modification of the invention. y s. I

The ventilator embodying the present 1nvention includes a hollow body comprising an inner section indicated in general by the reference character A and an outer section indicated in general by the reference chars acter B. Both of the sections are preferably stamped or otherwise formed 'from' sheet metal and the section A comprises a flat body portion 1 having a substantially segmental opening 2 formed therein, the arcuate \vall. fo-f the'opening having an an- 6o gular extent of less than asenii-circle whereby they axis of the body will-bespaced inwardly from the chordal wall of the opening, ,which wall is indicated by the numeral 3. The body 1 is provided'- with a periph- 65 eral. laterally extending flange 4 terminating'in an outwardly extending peripheral flange 5 formed vat suitable intervals with openings G, the purpose of whichv will be presently explained. Thesection B of the body comprises a fiat. body portion v7 corresponding to the body'portion 1 of the section A and this body portion is provided A with a segmental opening '8 corresponding tolthe opening 2, theV chordal wall 9 of the 7,5 opening S being spaced from the axis of the body as in the instance of the corresponding wall 3 ofV the `opening 2. The

Vmaterial of the wall or body'7 below the i chordal wall of the opening is so stamped and bent to extend inwardly as to form a lspacing member 9a having one or more openings 9b therein through which air currents may pass withoutinterference. The body portion 7 is provided with a flange 10 corre- 85 sponding to the flange 4 and terminating in a flange 11 corresponding to flange 5. The flange llv is formed at suitable intervals with openings 12 corresponding to the openings. Gand these openings 12 are preferably 90 punched or otherwiseformed in the Aflange 11 in such manner that the material of the flange will not be removed but will be forced inwardly to form ay relatively sharp edge 13 which serves a purpose to be pres- 95 ently pointed out. An annulus V14 is disposed against the outer side of the flange 5 l and an annulus 15 is disposed'against the outer side of the flange 11 and securing screws 16 `are fitted through openings formed in the annulus 14 and through the4 openings G and 12 and are threaded into openings or sockets formed in the annulus 15 as clearly shown in Fig. 2 of the drawings. Prior vto securing the parts together by the screws 16, the curtain in which the ventilator is to be. arranged and which is indicated by the numeral 17, has a Circular opening 18 cut therein and the sections A and B are disposed respectively againstv the ,11C

inner and outer surfaces of the curtain with the flanges 5 and 11 resting against said surfaces surrounding the opening 18, after which the annuli 14 and 15 are placed in position and the parts secured by means of the screws 16. As the screws are tightened Vthe sharp edges 13 surrounding the openn ings 12 are caused to bite into the material of the curtain and in this manner the curtain is prevented from being pulled from engagement between the flanges 5 and 11. In assembling the parts in the manner above stated the sections A and B are so relatively disposed that the chordal walls and '9 oi? the openings 2 and S respectively will be relatively otl'set at opposite sides of the axis of the body asia` whole although in parallel relation to each other and by reason of this relative disposition of the sections 'A and B it will be impractical for one standing in the aisle of the sleeping car to view the occupant of the berth through the said openings 2 and 8 as in the arrangement of the ventlators in the upper portion of the curtain the opening 2 will be located above the axis of the body and the opening 8 will be located below the said axis and in the arrangement of the ventilators in the lower portion of the curtain the opening 2 will be located below the axis of the body' and the opening 8 above the same.

In order that the opening 2 may be partly or wholly closed whenever so desired by the occupant of the berth, a segmental damper plate 19 is disposed against the inner face of the body portion V1 of the section A and is held in place by means of the stem 20 of a finger knob 21. A spring finger 22 car= ried by the stem 2O bears against the plate 19 and serves to connect the plate for rotation with the said stein and inasmuch as the ventilators are arranged within the curtain 17 in such manner that the section A of the ventilators will be innermost, theoccupant ofV the berth may readily adjust the damper plate 19 by turning the finger knob 21.

In addition to arranging the ventilators in the curtains for the berths of the car the ventilators may also be arranged in the window panes and when so arranged it is preferable that the opening 2 of the section A of each ventilator be covered by a Jforaminous sheet for example, a sheet of wire mesh as indicated at 23 and clearly shown in Figs. 4 and 5 of the drawings, this foraminous sheet of material serving to prevent the entrance of cinders and insects into the car and yet permittingthe free passage of fresh air.

In that Vcrm` of the invention shown in Figs. 4 and 5 of the drawings as well as in the form shown in Fig. 6, the parts which correspond to the parts in the form Shown in Figs. 1 to 3 inclusive, are indicated by like reference numerals and in that form shown in Fig. 6 the arrangement is substantially the sameV as shown in Figs. 4 and 5 of the drawings, the damper plate 19, however, being located exteriorly of the casing or hollow body of the device and a iler of wood or any other suitable material, indicated by the numeral 24, is disposed within the lower portion of the said body and is provided with a downwardly and outwardly inclined face 25 extending from the lower or chordal edge of the opening y2 in the section A to the loweror arcuate wall of the opening 8 in the section B. By reason of the provision of this iiler having the inclined face 25 any rain water driven in through the screen 23 and opening S will strike the said face and be carried downwardly and discharged through vthe lower portion of the said opening S and will, therefore, be prevented from collecting in the lower portion of the device.

Fig. 1 ofthe drawings clearly illustrates the arrangement of the ventilators within the curtain of the car and it will be understood that the curtain may be folded and stored in the usual manner without interference by the Ventilating devices and that likelihood of the said devices being collapsed 'or crushed is obviated inasmuch as the bracing members 9a serve to relatively brace the sections comprising the device.

Having thus described the invention, what is claimed as new is:

1. In a ventilator, a hollow body com# prising Vassembled sections provided each with an opening, said openings being oifset at opposite sides of the axis of the'body,

a linger knob having a stem fitted to the wall of one section, and a damper plate carried by the said stem and rotatable therewith and arranged to be moved into and out of position to close the said opening in the said wall.

2.V A ventilator of the class described comprising a hollow body consisting of asse1n bled sections, the said sections being provided with marginal circumscribing flanges, an annulus disposed against the outer side of each flange, securing elements fitted through the flangesand through the annuli, A

the said sections being Ventilating openings, and a damper plate carried by one of the sections and movable to control the passage or' air through the opening therein. Y p 3. In a ventilator of the class described, a body having spaced walls, the walls being provided with Ventilating openings, a damper plate movable to control the passage of air through the openings in one wall, and a. bracing member extending between the walls. Y

V4. In a ventilator of the class described, a hollow body comprising assembled sections having marginal ianges arranged to receive between them the edge of av sheetv -the said sections having Ventilating openings formed therein.

5. In a Ventilator, a hollow body having relatively displaced openings in its opposite 10 walls for the passage of air currents, the

opening in one wall being located in the lower portion thereof and the opening in the other wall being located in the upper portion thereof, and a water deflecting member arranged within the body and arranged to direct water entering the body outwardly therefrom through the opening in the rstmentioned wall.

In testimony whereof, I afx my signature.
